I am just starting to grow breasts and needed sports bras for yoga. These looked right in the photos and worked out perfectly. I walk for exercise and I also do yoga and my breasts are AAs. The bras are a little difficult to put on, I don't have big hips so I can pull them on from below, but otherwise they are comfortable, fit my breasts perfectly, and make my breasts appear more firm and shapely under tees. They also work with my tank tops and blend right in with them. They would probably look good alone, as well. I have broad shoulders and a 36 inch measurement under my breasts and the XL was perfect. There is also room to grow, so I feel comfortable that, even if my breasts grow larger, there will be room in these bras for them. All in all, an A++.
